Win7 64-bit CHM

Recently under a few of the Hu data, are CHM format, but in the Win7 64, are not shown inside the audio and video flash, such as the control, although the source file to open the way the video file, but very troublesome.

Online seems to meet the people are not a lot of basic to find several related posts. The main problem is the CHM open program question, borrow the Baidu CHM to explain the following

A CHM is a shorthand for English "Compiled help Manual", which is "compiled assistance files." CHM is Microsoft's new generation of Help file format, using HTML as source text, Help content in the form of a similar database compiled storage.

CHM file format is the Microsoft 1998 introduction of the HTML file features of the Help file system to replace the previous WinHelp Help system, it is also a Hypertext identification language, in Windows 98, the CHM type file is referred to as "compiled HTML Help file." The CHM also supports Javas cript, VBs cript, ActiveX, Java applets, Flash, common graphics files (GIF, JPEG, PNG), audio and video files (MID, WAV, AVI), etc. that are supported by IE browsers. And can be linked to the Internet through URLs

Simply speaking, Windows comes with the Help file format, which is opened by hh.exe this file, by default, calls%windows%/hh.exe to handle, for 64-bit Windows, there are actually 3 hh.exe, located in

%windows%/hh.exe,

%windows%/system32/hh.exe and

%windows%/syswow64/hh.exe, where the top 2 are 32-bit hh.exe (17k), only

%windows%/syswow64/hh.exe (15k) is the 64-bit program, to solve, need to use 64-bit hh.exe overlay

%windows%/hh.exe's

Pay attention to overwriting before backup, and if used directly

%windows%/syswow64/hh.exe cover to

%windows%/hh.exe, there should be a hint can not operate and so on, this is because, this file is the default group is Trustinstaller, we generally log in to the user or administrator, to modify, you need to right click

%windows%/hh.exe Properties, click Security--> Senior--> owner--> Edit, change owner to administrator, OK, back to Security tab, click Edit, Put Full control on hook, OK, Then you can cover it with a 64-bit hh.exe. After overwriting, it should be normal to open the CHM again.
